Description

A kind of composition comprising perfluoropolyether active constituent
Technical field
The invention belongs to hard substrate surface soiling processing technology fields, and in particular to one kind comprising perfluoropolyether activity at The composition divided.
Background technique
Perfluoropolyether active constituent is commonly used to carry out protective treatment to substrate, to obtain Water-proof and oil-proof and antifouling characteristic. Such as the transparent optical device (such as mobile phone glass screen) of touch type electronic display device, it is often contacted with finger, is easy to be referred to The pollution such as line, sweat, greasy dirt, device surface is after perfluoropolyether active constituent protective treatment, and dirt is without using solvent In the case of can also facilitate removal, avoid the damage that may cause using solvent to display device, maintain the view of display device Sense.Such as patent CN1284105 discloses a kind of antifouling coating composition for antireflective surfaces, patent CN101501046 Disclose a kind of composition of novel perfluoro polyether silicone, patent CN102666759 discloses a kind of for optical substrate Surface treating composition.
But perfluoropolyether active constituent, which usually requires to be dissolved or dispersed in fluid media (medium), just can be carried out surface-treatment applications, This relates to the material (being hereafter referred to as decentralized medium) for serving as carrier for active principle, diluent, decentralized medium or solvent.This point Dispersion media should be able to promote transfer, transmission of the active constituent in expected use, have no effect on the effect of active constituent；Or at least It should be able to promote transfer, the transmission of at least one active constituent, and not have a negative impact to the effect of active constituent.When making Used time, since these decentralized media will be volatized into atmosphere, the environmental characteristics of decentralized medium material become to be increasingly subject to Concern.It is a large amount of to make great efforts to be dedicated to exploitation to be 0 to ozone depletion potential (ODP) and to global warming potential between spending the more than ten years (GWP) lesser decentralized medium material.In addition to having and to consider to be conducive to environmental characteristics, it is used as the material of decentralized medium further preferably With relative to the inertia of one or more active constituents, hypotoxicity and low combustible.
Decentralized medium is needed come the coating layer of deposit perfluoro polyethers active component by the method for coating, optional dispersion is situated between Aromatic hydrocarbon solvent (such as double-trifluoro of matter such as perfluocarbon (such as perflexane, PF 5070 and perfluorooctane), fluorine richness Toluene), partially fluorinated hydrocarbon solvent (such as 2H, 3H- perflenapent) and hydrofluoroether etc..Typically, fluorination dispersion will be dissolved in Very thin active constituent dope layer is generated in very dilute solution coating to substrate of active constituent in medium.Therefore, A large amount of solvent is discharged into atmospheric environment.However, the big above-mentioned solvent in portion point is not 0 to ozone depletion potential (ODP), to the whole world The potentiality (GWP) that warms is larger.
Perfluoro butyl methyl ether (7100) and perfluoro butyl ether (7200) ozone depletion potential (ODP) are 0, to global warming Potentiality (GWP) is smaller, therefore is identified as the ideal dispersion medium of perfluoropolyether active constituent, patent CN1284105, CN101501046 and CN102666759 etc. is all made of 7100 as decentralized medium.Secondly, perfluorobutyl methyl ethers and perfluoro butyl Ethylether surface tension is low, viscosity is low, is easy to be formed in substrate surface processed and uniformly sprawl；But also there is evaporation latent heat Advantage low, drying time is short avoids solvent and retains the destruction that may be generated to substrate for a long time；Its is non-combustible, is a kind of On environment, there are few the environment-friendly type solvents of influence.However, perfluorobutyl methyl ethers and perfluorobutyl ethyl ether use electrofluorination work Prepared by skill, can generate more waste in production technology complexity, preparation process.Thus its is at high cost, production environmental protection pressure is big.Mirror In this, it is badly in need of searching and is readily produced, waste is not generated or generated less in production process and substitution solvent at low cost.
